About Sound Levels
Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.

Hazardous Location Upblast Roof-Mount Exhaust Fans
With a UL-listed motor, these fans can be used in hazardous environments with combustible gases and dust to draw stagnant and humid air out through your roof, forcing it up and away from its surface.
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.
Belt-drive fans are quieter and last longer than direct-drive fans because their components can be replaced if they’re worn or damaged.
